I have updated the name to work with Ninja Dojo.If you have Ninja Dojo, You can simply copy the script in the NinjaDojo directory. Ninja Dojo will automaticaly source the script and create a button in the NinjaDojo window.

UV_Ninja mapper:1. Generates UV's based on 90 degree rotations. So depending on your camera view it will determine which direction to apply the mappping. 2. Map to a specific pixel ratio by finding the texture applied to the object/faces and adjusting the uv's to the pixel ratio. It works on square and non square textures.3. Scales UV's to a specific pixel ratio4. Automatically unfold shells. 5. Cut UV's bases on edge selection.
